Matt Phillips has a hamstring injury and is replaced by Jay Rodriguez, while 19-year-old defender Max Melbourne - who is yet to feature for the Baggies in the Premier League - takes a spot on the bench.
Kieran Gibbs came off during the comeback draw with Newcastle on Tuesday with a gash to his thigh but has been passed fit to start for the Baggies at The Hawthorns.
Meanwhile, Roy Hodgson makes two changes to the Eagles side that earned a first away point of the season at Brighton & Hove Albion last time out as James McArthur and Martin Kelly come in for James Tomkins and Yohan Cabaye.
Damien Delaney had an operation on Friday and joins Lee Chung-yong and Connor Wickham on the sidelines, while Scott Dann has fallen ill overnight so Hodgson only has five substitutes to work with today.
